DETAILED DESCRIPTION

The detailed description provided below in connection with the appended drawings is intended as a description of the present embodiments and is not intended to represent the only forms in which the present apparatus may be constructed or utilized. However, the same or equivalent functions and sequences may be accomplished by different embodiments or a combination thereof.

Mobile wireless devices, such as mobile phones, laptops, tablets, smart watches and other smart wearables or cars with an on-board navigational system may need an integrated circuit card. It is also possible to use an external smart card reader for reading an integrated circuit card.

Often an integrated circuit card or a smart card may be any of a Subscriber Identity Module card (SIM card), a memory card, an identity card or a card which is suitable for making purchases, etc. The cards may be of different sizes. For example, the SIM card has been standardized and has four typical sizes according to the standards: full-size SIM 1st form factor (1FF), mini-SIM 2nd form-factor (2FF), micro-SIM 3rd form-factor (3FF), and nano-SIM 4th form-factor (4FF). Similarly, memory card families have been standardized into various sizes which may be characterized as standard, mini, micro, nano etc. Some pieces of electronic equipment using the integrated circuit card may also accept more than one integrated circuit card. In the following paragraphs, an abbreviated term “IC card” is used for an integrated circuit card which is intended to represent all types of integrated circuit cards of all sizes and varieties, including, but not limited to, SIM cards, memory cards, smart cards, payments cards, etc.

Typically, the IC card is removed by a user. For this reason, it may be desirable to provide an apparatus for a user to safely remove and replace the IC card without the risk of corrupting the IC card, such as a SIM card. There is a risk of data corruption if the connection to the IC card is unexpectedly interrupted. This may happen when the user ejects, completely or partially, the IC card while the apparatus holding the IC card is still on and possibly reading the IC card. In some devices, a switch may be used to give a warning to the program software before the user ejects the IC card. Further, another switch may be used to detect that the IC card is fully inserted. The warning may be used to shut down the apparatus. Further in some apparatuses, two separate devices may be used; one for giving the warning and another one for detecting that the IC card is fully inserted.

FIG. 1A is a schematical illustration of an embodiment, where a tray 3 is in a retracted closed position inside an apparatus 1 a. FIG. 1A represents an initial stationary position of the tray 3. The apparatus 1 a comprises a housing 2 and the tray 3 which is connected to the housing 2 in a movable manner. The tray 3 has a retracted closed position and an ejected open position with respect to the housing 2. Further, the apparatus comprises an ejector 4 configured to eject the tray 3 to the ejected open position. The ejector 4 may be a lever 401 or a similar type of device configured to push the tray 3 to the ejected open position. The tray 3 may carry for example two IC cards. The tray 3 may carry a SIM card 11 and additionally or alternatively a memory card 12 as illustrated in the example of the apparatus 1 a in FIG. 1A. The SIM card 11 and the memory card 12 are releasably attached to the tray 3 and to slots 303, 304.

FIG. 1B is a schematical example illustration of an embodiment, where the tray 3 is in a retracted closed position and where an opening tool 6 is inserted inside the apparatus 1 a. Further, the apparatus 1 a comprises a push member 5 configured to operate the ejector 4 to eject the tray 3 to the ejected open position when an external force Fe is applied to the push member 5 with the opening tool 6. The push member 5 may be a rod or cylindrical shaped solid piece or a plate with a shaped portion for receiving the external force Fe and for closing the switch 7. In some embodiment, the push member 5 may be made out of metal or plastic. The shaped portion may be formed by bending, whereby the shaped portion is a bent portion 501 as illustrated in FIGS. 1A and 1B. The push member 5 has a first position and a second position, wherein the push member 5 is in the first position when the tray 3 is in the retracted closed position. The push member 5 is configured to receive the external force Fe for moving the push member 5 into the second position and to operate the ejector 4 to eject the tray 3 to the ejected open position when the push member 5 is moved to the second position. The push member 5 is further configured to stay in the second position and maintain the second position even when the external force Fe is removed. The tray 3 comprises a handle 301 comprising an opening 302 structured to receive the opening tool 6 for applying the external force Fe with the opening tool 6 to eject the tray 3. The opening may be, for example, a through hole or similar type of structure for receiving the opening tool 6. The opening tool 6 may be, for example, a pin or a bar or similar type of structure. The detection of insertion of the opening tool 6, which indicates that the tray 3 is about to be ejected, and the detection of the tray 3 being in the closed retracted position is enabled by a switch 7. The switch 7 has a first electric position and a second electric position. The first electric position, illustrated in FIG. 1B and indicated with an arrow 14, is a closed position of the switch 7. The second position illustrated in FIG. 1A is an open position of the switch 7. The switch 7 is configured to receive the external force Fe and to switch to the first electric position in response to receiving the external force Fe, and the push member 5 is configured to maintain the switch 7 in the first electric position in response to the push member 5 being moved to the second position.

When the tray 3 is returned back to the retracted closed position by the user, the push member 5 is moved back to the first position, which causes the switch 7 to switch from the first electric position to the second electric position. The switch 7 comprises a first electric contact element 701 and a second electric contact element 702. When the external force Fe pushes the opening tool 6 up to the position of a first bent portion 7013 of the first electric contact element 701, the opening tool 6 causes the first electric contact element 701 to close the switch 7 by moving the first electric contact element 701 into contact with the second electric contact element 702. An electrical connection between the first electric contact element 701 and the second electric contact element 702 is enabled before the external force Fe is applied to the push member 5, which enables information to be indicated that the tray 3 is about to be ejected. In another embodiment, opening 302 may be arranged into the housing 2 (not illustrated in FIG. 1B), whereby the handle may be structured narrower compared to the handle 301 illustrated in FIG. 1B.

In an embodiment, the electric contact elements 701, 702 may be, for example, contact springs. The contact elements may be made out of metal and they may have a gold plating on the surface of the metal. The push member 5 may be made out of a metal plate or a plastic plate, whereby the push member 5 is a push plate.

In an embodiment, the first electric contact element 701 is fixed from a first end 7011 and a second end 7012, for example, to soldered joints. The second electric contact element 702 is fixed from an end 7021, for example, to a solder joint. The first electric contact element 701 functions as a spring which is able to bend and return back to its initial position. Also, the second electric contact element 702 may function as a spring. A second bent portion 7014 moves in contact with the second electric contact element 702 when the first electric contact element 701 is pushed by the opening tool 6 from the first bent portion 7013. Correspondingly, the second electric contact element 702 moves when it is pushed by the first electric contact element 701. A contact point between the opening tool 6 and the first bent portion 7013 is indicated inside a circle 15. The movement of the first bent portion 7013 is indicated with the arrow 14. The switch 7, when connected, closes an electric circuit 8 of a circuit board 9, enabling a first signal S1 indicating, that the tray 3 is about to be ejected. The first signal S1 may be a power off signal transmitted to a control unit 10 or a software module, such as a computer, which safely switches off the apparatus 1 a.

FIG. 1C is a schematical example illustration of an embodiment, where the tray 3 is in an ejected open position and where the opening tool 6 is inserted inside the apparatus 1 a. The opening tool 6 is inserted to its extreme position inside the apparatus 1 a. When the opening tool 6 is pushed further inside the apparatus 1 a, it causes the ejector 4 to move, which pushes the tray 3 to the ejected open position. The ejector 4 may comprise a lever 401 comprising at least one pivotal connection 402 enabling the pivoting of the lever 401. The pivoting of the lever 401 causes the moving of the tray 3 to the ejected open position when the lever 401 is pivoted around the pivotal connection 402 in response to an external force Fe applied to the push member 5 with the opening tool 6. The pivotal connection 402 may be, in some embodiments, a hole around a shaft, which may function as a bearing. The shaft may be connected to the housing 2. The bent portion 501 of the push member 5 pushes a third bent portion 7015 of the first electric contact element 701 keeping the switch 7 closed. This contact point is indicated inside a circle 15 a. The push member 5 is configured to maintain the switch 7 closed when the tray 3 is fully ejected to the open position.

FIG. 1D is a schematical example illustration of an embodiment, where the tray 3 is in an ejected open position and where the opening tool 6 is removed from the apparatus 1 a. The push member 5 is configured to maintain the switch 7 closed when the tray 3 is fully ejected to the open position even after the opening tool 6 is removed by the user. In the above explained FIGS. 1B to 1D, the switch 7 is continuously connected. In some embodiments, the apparatus may be configured such that the switching of the switch 7 is opposite to what is disclosed in embodiments illustrated in FIGS. 1A to 1D. In this embodiment, the switching of the switch 7 may be configured in such a way that firstly the switch is opened when the external force Fe of the opening tool 6 is applied to the switch 7 and secondly the switch 7 is closed when the tray 3 is returned back to the retracted closed position (not illustrated in FIGS. 1A to 1D).

FIG. 1E is a schematical example illustration of an embodiment, where the tray 3 is returned back in a retracted closed position and where the opening tool 6 is removed from the apparatus 1 a. The embodiment illustrated in FIG. 1E is similar to the embodiment illustrated in FIG. 1A with the exception that a second signal S2 is enabled, indicating that the tray 3 is back in the retracted closed position. The tray 3 is returned back to the retracted closed position by the user pushing the handle 301 of the tray 3. The push member 5 is configured to open the switch 7 by causing the first electric contact element 701 to disconnect contact with the second electric contact element 702 when the tray 3 is returned back to the retracted closed position. When the bent portion 501 of the push member 5 is no longer in contact with the first electric contact element 701, the first electric contact element 701 moves to its initial position and disconnects the switch 7. The switch 7, when disconnected, enables a second signal S2 which may comprise a software wake-up signal. The second signal S2 may be transmitted to a control unit 10 after the first signal S1 has ceased. The second signal S2 indicates that the tray 3 is fully inserted and the power of the apparatus may be safely turned back on. In some embodiment the second signal S2 is transmitted to the software of the control unit 10.

FIG. 2A is a schematical example illustration of an embodiment, where a tray 3 b is in a retracted closed position. FIG. 2B is a schematical example illustration of the apparatus 1 b where the tray 3 b is in a retracted closed position and where the opening tool 6 is inserted inside the apparatus 1 b. The apparatus 1 b illustrated in FIGS. 2A and 2B is similar to the apparatus 1 a illustrated in FIGS. 1A and 1B with the exception that an ejector 4 b is different and it is located in a different place in the apparatus 1 b. Another exception is that no push member is utilized in the structure of the apparatus 1 b. The switch 7 b is disconnected in FIG. 2A. Similar to the embodiment illustrated in FIG. 1B, in FIG. 2B, the opening tool 6 causes the closing of the switch 7 b. The ejector 4 b is in connection with a handle 301 b. The ejector 4 b is configured to push the handle 301 b when the tray 3 b is ejected. The ejector 4 b, in some embodiments, may be a lever 401 b, is located near the handle 301 b. The lever 401 may comprise a rotation stopper 407 b which limits the rotation of the lever 401 b to a predetermined position.

FIG. 2C is a schematical illustration of an embodiment, where the tray 3 b is in an ejected open position and where the opening tool 6 is inserted inside the apparatus 1 b. The apparatus 1 b illustrated in FIG. 2C is similar to the embodiment illustrated in FIG. 1C with the exception that an extension 405 b of the lever 401 b maintains the switch 7 b closed. When the tray 3 b is in the ejected open position, the switch 7 b is closed by the ejector 4 b even after the opening tool 6 is removed. The rotation of the lever 401 b is illustrated with an arrow 14 b. The rotation stopper 407 b limits the lever 401 b from being rotated too far away from the first electric contact element 701 b. The lever 401 b is returned back to the initial position illustrated with a dashed line after the user removes the opening tool 6 and after the user has pushed the tray 3 b back to the retracted closed position. The ejector 5 b is configured to maintain the switch 7 b in the first electric position when the ejector 5 b is moved from the first position to the second position. When the tray 3 b is returned back to the retracted closed position by the user, the ejector 5 b is moved back to the first position which causes the switch 7 b to switch from the first electric position to the second electric position. The ejector 4 b is configured to open the switch 7 b by causing the first electric contact element 701 b to disconnect the contact with the second electric contact element 702 b when the tray 3 b is returned back to the retracted closed position. The switch 7 b is opened when the extension 405 b is no longer pushing the first electric contact element 701 b.

FIG. 3A is a schematical example illustration of an embodiment, where a handle 18 c is in a shortened closed position and where the opening tool 6 is inserted inside the apparatus 1 c. The embodiment illustrated in FIG. 3A is similar to the embodiment illustrated in FIG. 1B with the exception that no housing is utilized and the ejector 4 c is configured to move only the handle 18 c, while the tray 3 c is kept in an unmoved position inside the apparatus 1 c. Another exception is that the tray 3 c is configured to carry three IC cards. Similar to the embodiment illustrated in FIG. 1A, the first electric contact element 701 c is moved by the opening tool 6 causing an indication of imminent ejection of the tray. This event is indicated with the circle 15. The handle 18 c comprises an opening 185 c for inserting the opening tool 6 inside the apparatus 1 c.

FIG. 3B is a schematical example illustration of an embodiment, where the handle 18 c is in an extended open position and where the opening tool 6 is inserted inside the apparatus 1 c. The handle 18 c has been connected to the tray 3 c in a slidable manner. The handle 18 c may comprise telescopic members 181 c, 183 c which may be structured inside guide rails 182 c, 184 c of the tray 3 c. The handle 3 c may be moved in relation to the tray 3 c by sliding the telescopic members 181 c, 183 c inside the guide rails 182 c, 184 c. The switch 7 c is configured to receive an external force Fec and to switch to the first electric position in response to receiving the external force Fec, and the push member 5 c is configured to maintain the switch 5 c in the first electric position when the handle 18 c is ejected to the extended open position. When the handle 18 c is returned back to the shortened closed position illustrated with the dashed line, the push member 5 c is moved back to the first position causing the switch 7 c to switch from the first electric position to the second electric position.

When the opening tool 6 is inserted far enough, the ejector 4 c which may be a lever 401 c, has pushed the handle 18 c away from the tray 3 c to the extended open position. The handle 18 c is moved when the lever 401 c pushes the first telescopic part 181 c with a first portion 403 c of the lever 401 c. The movement of the lever 401 c causes the sliding of the handle 4 c to the extended open position when the lever 401 c is pivoted around the pivotal connection 402 c. Similar to the embodiment illustrated in FIG. 1C, the opening tool 6 pushes a push member 5 c which operates the ejector 4 c. When the handle 18 c is ejected to the extended open position and the push member 5 c is in its possible extreme position, the first electric contact element 701 c is kept in contact with the second electric contact element 702 c by the push member 5 c, which is indicated with the circle 15 a. When the handle 18 c is pushed back to a shortened closed position by the user, also the push member 5 c is pushed back to its initial position, whereby the push member 5 c opens the switch 7 c by causing the first electric contact element 701 c to disconnect the contact with the second electric contact element 702 c. The shortened closed position is illustrated with dashed lines in FIG. 3B.

FIG. 4A is a schematical example illustration of an embodiment, where a tray 3 d is in a retracted closed position inside the apparatus 1 d. FIG. 4B is a schematical example illustration of an embodiment, where the tray 3 d is in a retracted closed position and where the opening tool 6 is inserted inside the apparatus 1 d. FIG. 4C is a schematical example illustration of an embodiment, where the tray 3 d is in an ejected open position and where the opening tool 6 is inserted inside the apparatus 1 d. The mechanism of the embodiments illustrated in FIG. 4A, FIG. 4B and FIG. 4C is similar to that of the embodiments illustrated in FIG. 1A, FIG. 1B, and FIG. 1C, with the exception that the push member 5 d is different from the push member 5 illustrated in FIG. 1A to 1C. Another exception is that the generation of indication of imminent ejection of the tray is done by the push member 5 d and not the opening tool 6. The tray 3 d comprises a plate 409 d between the ejector 4 d and the tray 3 d and at least one spring 408 d between the plate 409 d and the tray 3 d. This forms a gap G between the ejector 4 d, such as a lever 401 d, and the tray 3 d. When the lever 401 d is rotated with the push member 5 d into a position where the gap G is pushed closed, the spring 409 d is compressed. When the gap G is closed, the switch 7 d is closed by the aid of the push member 5 d pushing the first electric contact element 701 d into contact with the second electric contact element 702 c. At this point, the tray 3 d is not yet moved. The connection point between the push member 5 d and the first electric contact element 701 d is illustrated inside the circle 15. Similar to the mechanism of embodiments illustrated in FIG. 1C, the switch 7 d is kept closed by the push member 5 d when the tray 3 d is fully ejected. The connection point between the push member 5 d and the first electric contact element 701 d is illustrated inside the circle 15 a. The push member 5 d opens the switch 7 d by causing the first electric contact element 701 d to disconnect the contact with the second electric contact element 702 d, when the tray 3 d is returned back to the retracted closed position.

FIG. 5A is a schematical example illustration of an embodiment, where a tray 3 e is in a retracted closed position inside an apparatus 1 e. FIG. 5B is a schematical example illustration of an embodiment, where the tray 3 e is in a retracted closed position and where the opening tool 6 is inserted inside the apparatus 1 e. FIG. 5C is a schematical example illustration of an embodiment, where the tray 3 e is in an ejected open position and where the opening tool 6 is inserted inside the apparatus 1 e. The embodiments illustrated in FIG. 5A, FIG. 5B and FIG. 5C are similar to embodiments illustrated in FIG. 4A FIG. 4B, with the exception that the gap is implemented differently. The housing 2 e comprises a flap 19 e which functions as a spring moving the ejector 4 e away from the tray 3 e. A gap G2 is thereby formed between the ejector 4 e and the tray 3 e. The operation in embodiments illustrated in FIGS. 5B and 5C is similar to the ones illustrated in FIGS. 4B and 4C and are not thereby explained further.

In one or more of the above embodiments, the tray 3, 3 b, 3 c, 3 d, 3 e or the handle 18 c of the apparatus 1 a, 1 b, 1 c, 1 d, 1 e may be ejected with an opening tool 6 by means of the ejector 4, 4 b, 4 c, 4 d, 4 e and may be pushed back by the user, and the apparatus 1 a, 1 b, 1 c, 1 d, 1 e comprises only one switch 7, 7 b, 7 c, 7 d, 7 e which firstly detects that the tray 3, 3 b, 3 c, 3 d, 3 e or the handle 18 c is about to be ejected and secondly detects that the tray 3, 3 b, 3 c, 3 d, 3 e or the handle 18 c is closed to the closed position. If the tray 3, 3 b, 3 c, 3 d, 3 e carries an IC card or IC cards, they may be removed from the apparatus 1 a, 1 b, 1 c, 1 d, 1 e, without the risk of corrupting the IC card. Even if the user ejects the IC card when the apparatus 1 a, 1 b, 1 c, 1 d, 1 e is powered, the ejection of the IC card may be done safely.

Further, the apparatus 1 a, 1 b, 1 c, 1 d, 1 e has a simple structure. The functionality of the switch 7, 7 b, 7 c, 7 d, 7 e may be accomplished by using only one structure and not two or more separate devices. In electronic equipment, space may be limited. When the number of parts is reduced in the electronic equipment, the electronic equipment may be constructed smaller. The reducing of components inside the electronic equipment is useful and may results in savings from an economical point of view.

The apparatus 1 a, 1 b, 1 c, 1 d, 1 e disclosed in the embodiments above is useful in a solution where the apparatus 1 a, 1 b, 1 c, 1 d, 1 e is used as a card tray module for an electronic communication device, such as a smart phone or a tablet or a smart wearable. The apparatus 1 a, 1 b, 1 c, 1 d, 1 e is particularly useful when the electronic communication device utilizes at least two IC cards. The IC card may be a subscriber identity module card (SIM card), a full-size SIM 1st form factor (1FF) card, a mini-SIM 2nd form factor (2FF) card, a micro-SIM 3rd form-factor (3FF) card, a nano-SIM 4th form-factor (4FF) card, a secure digital card (SD card), a mini secure digital card (miniSD card), a micro secure digital card (microSD card), a memory card, a storage card, and an expanded external memory card.
